IMXRT1170-EVK debug failed:chip initialization failed - Ef(34): Timed-out initializing flash.

Hi, all:

I am trying a demo from the official website of Qt for MCUs. After successfully compiling an ELF and flashing it, the board can no longer be connected.

Here is the output log:

I tried change to serial boot loader, but it still not work.

The attachment contains the ELF file that I compiled.

What do I need to do to recover the MIMXRT1170-EVKB ?

Thank you!

Hello @pupu_ji ,

The output log that you provide me, occurs commonly when the core has in an unknown state and the debugger can't stop them, this can happen in low power states or if the project has an issue in any clock configuration.

To recovery your EVKB you can follow this application note ( RT board recovery for debugger connect issues - NXP Community). Although the application note uses the MIMXRT1060-EVK, it's the same with MIMXRT1170-EVKB. Also, after of recover the EVKB, you can try writing an SDK example. It could be the example called "Iled_blinky_cm7", this in order to corroborate that the EVKB works properly.

Also, if you experience any issue, do not hesitate to let me know.

BR,
Habib.

Hello,

I got the same issue and when I apply the two proposed solutions I get the following errors:
